Abstract
The use of Trichoderma spp. as a substitute has the potential to reduce the reliance on synthetic fertilizers and increase plant yield. Therefore, this study aimed to obtain (1) the types of Trichoderma spp., applicable rates, and their interactions that can improve agronomic yield and pyruvate content, as well as (2) the relationship between these characteristics and yield ha-1 of Samosir shallot. It was conducted in Dolok Martumbur Village, Muara Subdistrict, North Tapanuli District, North Sumatra Province, Indonesia, from June to December 2021. The Factorial Randomized Block Design was selected within three replicates in this study. Individual isolates of Trichoderma (T. harzianum, T. virens, T. viride, and T. asperellum and their applicable quantities from 0 to 60 g polybag-1 were the two variable parameter employed in current search. The data were processed with ANOVA, followed by DMRT at P<0.05, and correlated with Pearson using IBM SPSS. Based on the results, the highest increase in agronomic yield and total pyruvate was found in T. asperellum isolate. There were increased roots fresh weight, number of bulbs, bulbs diameter, and total pyruvate by 40.23; 15.71; 15.49; and 23.34% along with increasing the isolate applicable rates up to 60 g polybag-1. Likewise, their interactions of T. asperellum isolate at a applicable rates of 20 to 40 g polybag-1 could be increased the highest bulbs weight, yield ha-1, and total pyruvate. Furthermore, root fresh weight, the number of bulbs, bulbs weight, and total pyruvate positively and significantly correlated with increasing yield ha-1.
